Cleaned up ST settings a bit. Can't use hardlinks to maintain both windows and mac keymaps, due to the 'super' key on macs. Duh.
Updated .gitignore to ignore tons of standard file types that should never be there. Also ignoring ST's Package Control.cache directory and the Package Control.last-run file.
Added support for powershell, fixed the duplicate line keymap
Added my powershell profile, which also loads posh-git
